If there is a a trailing align statement in a code section we may
output data padding with a data mapping followed by a code alignment
with a code mapping. The literal pool may then be output with a code
mapping symbol which will cause it to be endian swapped in a big-endian
configuration. When outputting a literal pool make sure that a data
mapping symbol is output in all cases.
